The AMD A4 PRO-3340B was a mobile processor with 4 cores, launched in December 2014. It is part of the A4 lineup, using the Kabini architecture with Socket FT3. A4 PRO-3340B has 2 MB of L2 cache and operates at 2.2 GHz. AMD is building the A4 PRO-3340B on a 28 nm production process, the transistor count is unknown. The silicon die of the chip is not fabricated at AMD, but at the foundry of GlobalFoundries. The multiplier is locked on A4 PRO-3340B, which limits its overclocking capabilities.
With a TDP of 25 W, the A4 PRO-3340B consumes only little energy. AMD's processor supports DDR3 memory with a single-channel interface. The highest officially supported memory speed is 1600 MT/s, but with overclocking (and the right memory modules) you can go even higher. For communication with other components in the computer, A4 PRO-3340B uses a PCI-Express Gen 2 connection. This processor features the Radeon HD 8240 integrated graphics solution.
Hardware virtualization is available on the A4 PRO-3340B, which greatly improves virtual machine performance. Programs using Advanced Vector Extensions (AVX) will run on this processor, boosting performance for calculation-heavy applications.
